Abstract: N-Monosubstituted 2'- or 4'-amino-4-alkoxy-diphenyl ethers, where the N-substituent is an arylmethyl group, are effective antioxidants in a wide variety of petroleum products and petroleum related products. Within the class of arylmethyl groups, heteroaryl groups are especially desirable, as exemplified by pyridinylmethyl and thienylmethyl.

Abstract: Imines of 2,4'-diaminodiphenyl ethers are effective antioxidants in petroleum and petroleum-related products. Especially desirable are 2,4'-bis-(N,N'-arylmethylideneamino)phenyl ethers, where the aryl moiety is a heteroaromatic group.

Abstract: A solder flux composition comprises a mixture of sarcosine and tartronic or tartaric acid dissolved in water and an aliphatic alcohol. Typically the acid-sarcosine weight ratio lies within the range 90:10 to 30:70 and the solution may contain between 5 and 20 weight percent of solids. The flux is employed for tin/lead soldering of a range of metals and alloys including copper, nickel and nickel-iron. Bidegradation of the flux is inhibited by the inclusion of lead carbonate, phenol or salicylic acid in the composition.

Abstract: A tool for forming a stepped blind hole in bone for receipt of a fracture reducing and stabilizing surgical implant. The tool comprises a small diameter drill portion axially adjustable with respect to a larger diameter reamer portion. A conical portion includes cutting surfaces to chamfer the entrance of the hole and also includes non-cutting portions which serve to limit penetration of the tool into the bone. The tool is cannulated to allow its use in conjunction with a previously installed Kirschner guide wire.

Abstract: An electron discharge tube evaporation cooling system in which part of a tube to be cooled is immersed in coolant in a boiler (15), the cooling system further comprising a condenser (18) for vapor generated in the boiler (15), and a coolant reservoir (11). The flow of vapor from the boiler (15) to the condenser (18) experiences resistance in the interconnecting pipe (17), producing in the boiler (15) a back pressure dependent on the dimensions of the pipe (17). In order that a desired level (40) of coolant in the boiler (15) can be obtained for a range of back pressures, the coolant is supplied to the boiler via an overflow system (16) having an adjustable overflow level. The overflow system (16) comprises a chamber (31) open to atmosphere at the top (34) and having at the bottom (33) an opening (36) through which an overflow tube (35) passes.

Abstract: N,N'-disubstituted 2,4'-diaminodiphenyl ethers are a potent antioxidant for petroleum products and petroleum-related products. In particular, the N,N'-dibenzyl derivative and other aromatic and hetero-aromatic analogs of the dibenzyl derivatives exhibit desirable antioxidant properties at levels as low as about 0.05% by weight.

Abstract: Acetoacetanilides and related beta-ketoacetanilides are effective antioxidants when used as additives in petroleum products and petroleum-related products. Antioxidant properties are displayed at levels as low as about 0.05 weight percent.

Abstract: Tilting the stabilizer at an extreme angle to the fuselage, with leading edge down, and controlling and varying engine thrust comprise a method for all-axis control of a generally conventional aircraft in ultra deep stall. The method is effective in recovery from unstable and unusual flight attributes and in landing emergencies; the aircraft may land in the ultra deep stall configuration or conventional flight may be resumed. So-called flying wing aircraft, where pitch control surfaces are incorporated with the trailing edge of the primary lift surface, are also controllable in ultra deep stall by the method of this invention.

Abstract: A tool for use in a can closing or seaming machine to adjust the spring pressure exerted by the can holding chuck spring is disclosed. The tool permits chuck spring adjustment in conjunction with a force gage in situ without necessitating the removal of the gage from the machine for each spring incremental adjustment as is necessary in the prior art. The tool is a self-contained unit which includes an axially guidable and turnable wrench member, the tool also serving as an adapter or spacer for positioning the force gage in the machine.

Abstract: Method for making a tire whose white sidewall portion is created by, selectively, providing a circumferential groove in the molded tire, buffing the surfaces of the groove, placing an adhesive in the groove, heating the tire about 138.degree. C. to dry the adhesive, bringing the tire temperature to about 100.degree. C. and, while rotating the tire with the groove in a substantially horizontal plane, directing a stream of white polyurethane stock into the groove by means of an applicator which is formed to direct the stock in differing volumes into the bottom of the groove and laterally against its corners and sides; the white sidewall strip so formed has the shape of a concave meniscus.

Abstract: Polyurethane pneumatic tires with colored sidewalls are produced by applying one or more elastomeric coatings thereto. A colored polyurethane elastomeric coating may be applied directly to the sidewall, but it may be applied to a primer elastomeric coating which is first applied and the colored coating is applied to it either before or after it is cured. The color of the colored coating may be produced by dyeing or pigmenting.

Abstract: A charge-coupled analogue delay line has a plurality of analogue storage locations, and a gating means, which may include charge-coupled shift register, for enabling input to and output from each of the storage locations in turn. The storage locations are formed on a semiconducting substrate and each has a diffused zener diode to act as a source of minority carriers and a priming electrode for drawing off and holding a charge of minority carriers from the zener diode. A sample-holding electrode, upon receipt of a gating signal by a gating electrode, receives from the priming electrode and holds a charge of minority carriers of magnitude indicative of the magnitude of the signal to be stored. An output electrode is arranged to transfer the charge held by the sample-holding electrode to a diffused output channel.

Abstract: Tilting the stabilizer at an extreme angle to the fuselage, with leading edge down, and varying engine thrust comprise a method for all-axis control of a generally conventional aircraft in deep stall. In an alternative embodiment, tilting the engines upward at an extreme angle to the fuselage and varying engine thrust comprise a method for all-axis control in deep stall.
